Le n\u00e9vrome de Morton est un \u00e9paississement b\u00e9nin (formation de tissu fibreux) du nerf digital plantaire commun situ\u00e9 \u00e0 l\u2019avant-pied. Il appara\u00eet le plus souvent entre le 3e et le 4e m\u00e9tatarsien et provoque des douleurs, une sensation de br\u00fblure et des engourdissements \u00e0 la marche ou lors du port de chaussures \u00e9troites.<\/p>\n\n\n\n

\n

Causes et facteurs de risque<\/strong><\/p>\n\n\n\n

Le n\u00e9vrome de Morton est caus\u00e9 par une pression ou une irritation r\u00e9p\u00e9t\u00e9e du nerf, entra\u00eenant un \u00e9paississement et une inflammation du tissu fibreux qui l\u2019entoure.<\/p>\n\n\n\n

1. Variations de la biom\u00e9canique du pied<\/strong><\/p>\n\n\n\n

\u2013 Pieds plats ou pieds creux, qui affectent la bonne r\u00e9partition des pressions sur le pied.<\/p>\n\n\n\n

\u2013 D\u00e9formations des orteils (par exemple orteils en marteau, hallux valgus), qui cr\u00e9ent une pression suppl\u00e9mentaire sur le nerf.<\/p>\n\n\n\n

2. Chaussures inadapt\u00e9es<\/strong><\/p>\n\n\n\n

\u2013 Chaussures \u00e9troites ou \u00e0 bout pointu, qui compriment les orteils les uns contre les autres.<\/p>\n\n\n\n

\u2013 Talons hauts, qui augmentent la pression sur l\u2019avant-pied.<\/p>\n\n\n\n

3. Sollicitations prolong\u00e9es<\/strong><\/p>\n\n\n\n

\u2013 Course, danse ou sports impliquant des sauts r\u00e9p\u00e9t\u00e9s, qui augmentent la friction autour du nerf.<\/p>\n\n\n\n

\u2013 Station debout prolong\u00e9e, en particulier sur des surfaces dures.<\/p>\n\n\n\n

4. Traumatismes et inflammations<\/strong><\/p>\n\n\n\n

\u2013 Ant\u00e9c\u00e9dents de traumatismes du pied ayant pu provoquer la formation de tissu cicatriciel autour du nerf.<\/p>\n\n\n\n

Sympt\u00f4mes<\/strong><\/p>\n\n\n\n

\u2013 Douleur \u00e0 l\u2019avant-pied, souvent d\u00e9crite comme une sensation de br\u00fblure ou de douleur lancinante.<\/p>\n\n\n\n

\u2013 Sensation de pr\u00e9sence d\u2019un petit \u00ab caillou \u00bb dans la chaussure.<\/p>\n\n\n\n

\u2013 Engourdissement ou fourmillements dans les orteils, en particulier au niveau du 3e et du 4e orteil.<\/p>\n\n\n\n

\u2013 Aggravation de la douleur lors du port de chaussures \u00e9troites ou apr\u00e8s une marche prolong\u00e9e.<\/p>\n\n\n\n

\u2013 Soulagement lorsque vous retirez vos chaussures ou massez le pied.<\/p>\n\n\n\n

Diagnostic<\/strong><\/p>\n\n\n\n

Le diagnostic repose sur :<\/p>\n\n\n\n

\u2013 Un examen clinique, au cours duquel le podologue exerce une pression sur la zone afin d\u2019\u00e9valuer la douleur et la sensibilit\u00e9.<\/p>\n\n\n\n

\u2013 Signe de Mulder :<\/strong> une pression est appliqu\u00e9e sur l\u2019avant-pied, et un clic caract\u00e9ristique peut \u00eatre provoqu\u00e9 en pr\u00e9sence d\u2019un n\u00e9vrome.<\/p>\n\n\n\n

\u2013 Examens d\u2019imagerie :<\/strong><\/p>\n\n\n\n

\u00c9chographie pour d\u00e9tecter l\u2019\u00e9paississement du nerf.<\/p>\n\n\n\n

Imagerie par r\u00e9sonance magn\u00e9tique (IRM), si les sympt\u00f4mes sont s\u00e9v\u00e8res ou si le diagnostic est incertain.<\/p>\n\n\n\n

Prise en charge et traitement<\/strong><\/p>\n\n\n\n

1. M\u00e9thodes conservatrices<\/strong><\/p>\n\n\n\n

\u2013 Changement de chaussures<\/strong><\/p>\n\n\n\n

\u2013 Choisir des chaussures larges avec une semelle souple qui ne compriment pas les orteils.<\/p>\n\n\n\n

\u2013 \u00c9viter les chaussures \u00e9troites, pointues ou \u00e0 talons hauts.<\/p>\n\n\n\n

\u2013 Semelles orthop\u00e9diques, qui aident \u00e0 r\u00e9tablir une anatomie fonctionnelle correcte du pied et \u00e0 d\u00e9charger la zone concern\u00e9e.<\/p>\n\n\n\n

\u2013 Physioth\u00e9rapie et \u00e9tirements<\/strong><\/p>\n\n\n\n

Exercices de renforcement pour am\u00e9liorer le soutien du pied.<\/p>\n\n\n\n

Thermoth\u00e9rapie ou massage, afin de d\u00e9tendre les muscles plantaires.<\/p>\n\n\n\n

\u2013 \u00c9viter les sollicitations excessives et adapter les activit\u00e9s.<\/p>\n\n\n\n

\u2013 M\u00e9dicaments anti-inflammatoires (ibuprof\u00e8ne, naprox\u00e8ne) pour un soulagement temporaire de la douleur.<\/p>\n\n\n\n

2. Traitements mini-invasifs<\/strong><\/p>\n\n\n\n

\u2013 Injections de cortisone : elles soulagent l\u2019inflammation, mais ne constituent pas une solution permanente.<\/p>\n\n\n\n

\u2013 Injections alcoolis\u00e9es (Alcohol Sclerosing Therapy) : traitement scl\u00e9rosant r\u00e9duisant progressivement la taille du n\u00e9vrome.<\/p>\n\n\n\n

3. Traitement chirurgical (dans les cas s\u00e9v\u00e8res ou persistants)<\/strong><\/p>\n\n\n\n

Lorsque les traitements conservateurs \u00e9chouent et que la douleur affecte significativement la vie quotidienne, une ex\u00e9r\u00e8se chirurgicale du n\u00e9vrome peut \u00eatre n\u00e9cessaire.<\/p>\n\n\n\n

Pr\u00e9vention<\/strong><\/p>\n\n\n\n

\u2013 Choix de chaussures adapt\u00e9es : confortables, avec un bon soutien et suffisamment d\u2019espace pour les orteils.<\/p>\n\n\n\n

\u2013 Repos r\u00e9gulier et \u00e9tirements pour \u00e9viter la surcharge des pieds.<\/p>\n\n\n\n

\u2013 Utilisation de semelles orthop\u00e9diques en cas de pr\u00e9disposition ou de variations anatomiques de l\u2019avant-pied.<\/p>\n\n\n\n

\u2013 \u00c9viter le port prolong\u00e9 de chaussures \u00e9troites ou \u00e0 talons hauts.<\/p>\n\n\n\n

Quand consulter le podologue<\/strong><\/p>\n\n\n\n

\u2013 Si la douleur persiste plus de 2 \u00e0 3 semaines malgr\u00e9 les changements de chaussures.<\/p>\n\n\n\n

\u2013 En cas d\u2019engourdissement important ou de sensation de br\u00fblure \u00e0 l\u2019avant-pied.<\/p>\n\n\n\n

\u2013 Si la sensation de \u00ab pierre dans la chaussure \u00bb devient de plus en plus marqu\u00e9e.<\/p>\n\n\n\n

\u2013 Si la douleur rend la marche difficile ou affecte votre quotidien.<\/p>\n<\/blockquote>\n\n\n\n

Le n\u00e9vrome de Morton<\/strong> est une affection douloureuse mais traitable. Les traitements conservateurs sont souvent efficaces, tandis que dans les cas avanc\u00e9s, la chirurgie peut offrir une solution d\u00e9finitive.<\/p>\n","protected":false},"excerpt":{"rendered":"
